At least there are a lot of launches these days, so you can target dates with some potential. I travel to the Space Coast of FL quite a bit. Best thing to do is to simply be aware of the schedules: https://spaceflightnow.com/launch-schedule/

Then plan your dates. Then hope. Last time I was down I really hoped to see the Falcon Heavy launch and two boosters land. It was scheduled for about 3:00 AM and night launches are super cool. Thought I would get to see two booster landings at night. They scrubbed three times in a row.... no luck. While I was there I did see a F9 launch during the day.

FL vacation is not easy or cheap. You can watch from anywhere nearby on the beaches, but Titusville or the Space Center itself is best. Cocoa Beach anywhere at the pier or North is great. Jetty Park is fantastic. You can always stay somewhere between the Cape and Orlando to save on cost, then make some Orland visits to tourism land.

Nothing exists, nothing except for me. In my struggle to understand how and why I am conscious, my mind invents all that I perceive, including the curious point that you have come along to ask this question. I remember a past that also does not exist. I anticipate a future that certainly does not exist. I exist. I exist here in a present moment that never ends. I perceive things near and distant in time and space, all constructs. Trying as I have for this moment of eternity, I can prove to myself no more than this.
